Breton was part of an initiative to start the CWHL. The league was spearheaded by players such as Allyson Fox, Kathleen Kauth, Kim McCullough, along with national team members Sami Jo Small and Jennifer Botterill. The players worked with a group of volunteer business people to form the CWHL by following the example of the National Lacrosse League. The league would be responsible for all travel, ice rental and uniform costs, plus some equipment. Breton would become the general manager and head of public relations for the Montreal Stars. On March 19, 2009, Breton was part of the Stars team that openly played for the Clarkson Cup for the first time. Montreal beat the Minnesota Whitecaps to claim the Cup.
